Abstract
Described are tools—including distractor, trial, chisel, and inserter—that may be used as a system for implanting a prosthetic intervertebral disc in a spine. The distractor moves vertebrae and may have angled forks optionally offset for visibility with removable jaws optionally matching desired lordotic angles. The trial tool(s) may fit within the distractor forks, include a lordotic angle, and may include a disc portion, an adjustable stop, and a feature to control movement of the disc portion relative to the adjustable stop. The chisel tool cuts grooves in the vertebral bodies, which grooves affix the disc to the vertebrae. The chisel(s) may fit within openings in the trial, where those openings also serve as a guide during the groove-cutting step. The inserter tool, optionally with a movable pusher, is used for inserting the prosthetic disc into the prepared intervertebral disc space.
